96 integra should I keep b18b1 or get b18c

My friend is abut to sell me a 96 integra for $1,200 and I just wanted to build a quick street car (maybe a bottom end rebuild, cold air intake and a turbo kit) and I was wondering if I should just use the original motor or a 180HP b18c. And if i went with the b18c how difficult of a swap would it be? Also I was wondering if the HP gain would be worth the hassle?
